Which of the following is part of the preventive measures in the remineralization protocol?

• A. Diet modification
• B. Extraction of non-restorable teeth
• C. Laser therapy
• D. Radiographs

Answer: (A)

Remineralization relies on allowing minerals to redeposit in enamel while minimizing the factors that cause mineral loss. The preventive part of this approach centers on reducing the acid and sugar challenges to teeth so that saliva and any applied minerals (like fluoride or CPP-ACP) can rebuild subsurface enamel. Diet modification directly achieves that by limiting fermentable carbohydrate exposure and acidic intake, thereby decreasing demineralization and giving the natural repair processes room to work. That’s why it fits as a preventive measure in a remineralization protocol.

The other options aren’t preventive steps for remineralization. Removing teeth that are non-restorable is a treatment decision, not a preventive measure to promote remineralization. Laser therapy isn’t a standard preventive component of remineralization protocols. Radiographs are diagnostic tools used to detect and monitor caries progression, not actions that promote remineralization.
